You live in Alaska, where it's dark 18+ hours a day for 1/4 the year and you have no night-sights? Are you hoping the aurora borealis is going to illuminate your target?
Night sights do not 'illuminate' anything of the target. That is what the flash light is for.
Night sights only help align the sights in darkness. But if that 'shadow' turns out to be your kids, well you will see why you need that light.
